we are committed towards offering a wide range of Arduino Pro Micro ATmega32U4 which allows the Micro to appear to a connected computer as a mouse and keyboard, in addition to a virtual (CDC) serial / COM port. This is a microcontroller board based on the ATmega32U4, developed in conjunction with Adafruit. Arduino Pro Micro ATmega32U4 contains everything needed to support the microcontroller; simply connect it to a computer with a micro USB cable to get started. Offered range has a 16 MHz crystal oscillator, 20 digital input/output pins, a micro USB connection, an ICSP header, and a reset button.
